I have a 1.2 trio of the lighter race and a single of the darker race that I've always kept separate. For space reasons I'm debating on combining them into a single tank, but have been questioning the ethics of doing so- I know they'll breed, and so I want to ask the community about what we feel our responsibility is in preserving genetics of captive populations of species but from distinct regions. Do we feel we have this responsibility? On the one hand I feel the captive populations would benefit from mixing the Gene's of these populations but do we want to preserve their distinctions? I'm very interested to know thoughts on this. Thanks!

It is a moral dilema, the first questions would be whats the harm ? will these animals or their offspring have any effect on the wild populations ? Does it matter if we lose specific races in captivity? Personally i think that each race has an intrinsic value which will be lost if they interbreed, however, if there is a very small population available in captivity with little genetic variation maybe the species can be secured by interbreeding. I dont think this should be an issue in the US atm with this species. As for maintaining distinct races for possible wild release in the future, who knows what will happen to their habitat. Maybe in the future all that will remain are captive descendants of our current pets, if we allow interbreeding we lose races, maybe they could be clawed back with future gene editing , maybe , maybe not, either way actions we take now have an impact in the future. Axolotl would be a good example, functionally extinct in their natural range, millions in captivity but worthless as they are hybrids.
Personally i would keep races seperate or destroy eggs.

I agree with Ian. In the past i've heard hobbyist's captive populations described as "genetically dead" to wild ecosystems, but nowadays those attitudes are changing. I know H. Cyanurus is not rare in captivity especially in North America, but there won't be any more (legal) imports so numbers could easily dwindle.
I think if I were in your shoes I would probably house them together unless I planned to breed them, I just wouldn't raise any of their offspring that might be produced accidentally.

This is exactly the insight I was looking for- something that would justify my hesitation. I kept second guessing myself, thinking I was bring overly cautious but I'm pleased to hear that others feel the same way. Thank you both so much for your opinions. Separate they shall remain (since I want offspring from the trio).

    Hi I recently rescued a lotl (i did weeks of research before rescuing) Hes mabey 5 or 6 years of age..the previous owner could not remember the exact age of him. I got him from her as he was or had been picked on by his tank mate another lotl who was bough with him from every younger age, I noticed one of his gills, a middle one at the end had split in two? And is slightly more floppy? He also appears or mabey I'm just over worried to mabey have lost some feathers, is that normal to lose some?...all levels in the tank are fine, but wondered if theres and advice anyone could give me as an experienced owner to a new one.

  • Axolotl Queen:
    @Lanalotl Sounds like the gills may have been nipped by the tank mate. If he is in his own tank and the parameters etc are all good, then he should grow them back and they should go back to full health and strength. However, depending on how old the injury is they may not fully grow back if they have been constantly nipped at.

    Can anyone tell me why this is happening? We just did a water change and after freaking out and whipping around the tank, an hour later they look like this. It won't let me send a pic. The edges of their gills are white and it looks like they have skin shedding off

    That sounds like severe skin damage. If you post a thread on the forum, you can attach pictures.

    It sounds like something went wrong with the water change, so this could be very dangerous. Did you use a dechlorinator? Could it be there are traces of chlorine or soap in the water? (Or for example, in the bucket you used?)

  • Murk:
    Normally, I would recommend taking them out of the tank asap and putting them in a tub with fresh water, but if there's something wrong with your tap water or dechlorinator, that might not help either. Do you have acces to bottled water or rain water?

    I think my axie is dying, he’s never had any issues before, I’ve had him 3 years, today I noticed some fluffy looking stuff coming from his genital area so I took him out of his tank and did a full tank clean to make sure the water wasn’t infected as I thought it was fungus and then I noticed he had a cut on his belly which was only small about 5 hours ago and now it’s spread to all of his belly, what do I do I’m freaking out

    Update about my axie, unfortunately he has died over night, he looked as if he was bruised allover his belly, his mucus layer had also started to come off.

    Hi I have 2 4in juveniles (I’ve had them about 2 weeks and they are doing well I think they’ve grown a little already honestly) but I am supposed to go on a 5-6 day vacation in October about 3-4 months from now. I am wondering how I should go about their care when I am gone. I thought about putting them in separate (fairly big) containers with live plants and/or bubblers with a fan in the dark and either fridging them (my last plan) but I am hoping to to either have someone I trust come feed them and turkey baste waste out or just leave them out and clean the containers before we leave and have someone come check on them once or twice. Does any of this sound like a good or bad idea? I want the best for them. All help appreciated :)

    Hi, so I have 2 male axolotls and about an hour ago they were both perfectly fine and now only one of them has his tail curling up and his gills are slightly curled?? But other than that they’re both acting normally

    Could be he's just excited, spooked or temporarily stressed, which could pass in a few hours. It could also be an indicator of other problems. Do you have any recent water parameters?

    Does anyone have any idea how to help with high ammonia levels? I have the API freshwater master kit and everything else’s test results were great besides ammonia. I did a 50% water change and I use API products including ammonia lock.

    Help! I got my first axolotl two days ago and they have stopped eating. They ate a few frozen blood worms the first day and haven’t eaten or been interested in food since. I feed them frozen blood worms and the tank is around 64 degrees. I do have a filter that moves sometimes and I noticed them swimming up to it, I have a new filter and a fan coming today or tomorrow. I leave the worms in the tank or a little bit before taking them out so I don’t know if they ate when I wasn’t looking. I know it takes a while for them to digest. Does anyone have any tips or knowledge they can share? The pet store I bought them from didn’t have gravel or sand in the tank so I’m not sure if theres an issue or if I’m just impatient. Thank you!

    @MuggleMiChu I would say try live black/blood worms untell they are full or just turn there head away ( that's what mine do) if that does not work try to get some live brine shrimp and see if they eat that. baby axolotl prefer live food over frozen food as the frozen food is too cold for them or they can't eat it in one go( that's if you do the blocks) mine eat chopped up frozen thawed shrimp. as for them not eating from what I have experienced with my second axolotl, I got her when she was about an inch long and she ate every day, when they start getting 3-4 inches long they will gradually slow down there eating. and if you really want to do substrate I would do sand because if they do ingest a little bit it won't hurt them.
